BIOCONVECTION IN CASSON FLUID FLOW WITH GYROTACTIC MICROORGANISMS AND HEAT TRANSFER OVER A LINEAR STRETCHING SHEET IN PRESENCE OF MAGNETIC FIELD

Abstract

A study related to bioconvection of magnetohydrodynamic boundary layer flow, heat and mass exchange of Casson fluid containing gyrotactic microorganisms above a linearly stretching surface is considered. The Partial differential equations which govern the physical situation are transformed into a system of coupled nonlinear ordinary differential equations using similarity transformations. Taylor’s series solution for momentum, energy, the diffusive concentration of nanofluid, and concentration of microorganism’s equations are obtained using the differential transform method and compared with numerical solutions. The effects of a range of non-dimensional parameters on bioconvection fluid flow and heat transfer are analyzed through graphs.
